This letter proposes a novel manually actuated mechanism to control the position and posture of a passenger for preventing accidents due to stroller tipping while ascending or descending steps. This mechanism is designed as a four-bar linkage, which uses the rotational torque applied to the stroller
This study describes a novel active rotary-legs mechanism for a stair-climbing mobility vehicle. We have previously developed a stair-climbing up and down wheelchair with lever propelled rotary-legs operated using the human upper body. The previous results indicated that the required torque for the
This paper describes a novel passive exoskeleton for voluntary sitting-standing posture transition for children with lower limb impairment. The design of the exoskeleton is based on the utilization of the center of gravity transition through the user's upper body motion. The passive exoskeleton powe…
There are a few types of step-climbing wheelchairs in the world, but most of them are large and heavy because they are power-assisted. Therefore, they require large space to maneuver, which is not always feasible with existing house architectures. This study proposes a novel step-climbing wheelchair…
